摘要： A sheet conveying apparatus permits keeping predetermined sheet intervals, even when sheet conveyance is temporarily discontinued and then resumed, after resumption of conveyance. The sheet conveying apparatus has a first roller which feeds sheets at predetermined sheet intervals, and a second roller which conveys a plurality of sheet fed from the first roller. After temporarily discontinuing conveyance of the plurality of sheets, conveyance of the plurality of sheets is resumed by use of the first roller and the second roller. The variation in the sheet interval caused when temporarily discontinuing sheet conveyance is corrected upon resumption of sheet conveyance.

摘要： In an image forming apparatus which requires the user to manually input sheet medium information, (when a bundle of sheets which include a plurality of types of print media are to be printed, the user must manually input setups of the image forming apparatus for each individual print medium. In manual setups by the user, some setups require user's knowledge about print media. When the user has made wrong setups, a print result cannot be obtained under an appropriate control condition Furthermore, when information about a print medium is sensed by the sensor without manual setups, the information cannot be often precisely detect depending on the type and thickness of the print medium, an environment, and the like, and it is consequently difficult to attain optimal image formation. It is an object of this invention to attain optimal image formation, saving user labor and shortening the print time by using a radio tag attached to the sheet medium. An image forming apparatus which forms an image on a sheet medium, has means for reading information from a information holding means, such as a minuscule radio chip, attached to the sheet medium, and means for manually inputting information of the sheet medium, and controls an image forming condition using either information.

摘要： The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.
